The tower row of eperturee ere eo diepoeed With reepect to the tire-brittle, heequeuti ittiii of the arms 14. A large opening 21 is dis posed at the center of the member 17 so that the flame therefrom is directed against the hot spot chamber 13.

The member 17 may be provided with flange portions 22 adapted to rest upon seats 'or ledges 23 in the troughs 15. Bolts 21 extending through the flanges 22 and the ledges 23 may be employed to removably attach the nozzle member 17 to the burner.

Each of the arms 14 of the fire pot may terminate in a tubular port-ion 21 having an external flange 25 adapted to be connected by suitable bolts 26 to a companion flange 27 at an end of a conduit 12.

Thus communication is afforded between the expansion chamber and the burner nozzle 17 through which fuel may issue for ignition. Each of the trough-shaped por tions 15 may be provided with removable fire brick linings or side walls 27 having their inner surfaces 28 sloping upwardly in an are from the troughs to provide flaring apertures for the distribution of heat waves.

When the upper fuel conducting manifold 10 is in place and secured by bolts 26 to the fire pot 11, fuel entering the pocket 18 will first be subjected to an intense heat and cracked and the gases thus formed guided through the conduits 12 to the nozzle plate or member 17 for ignition.

Fuel may be ledto the pocket 13 by means of a pipe 29 connected wit-h a fuel source (not shown) of any suitable character. Any desirable fluid fuel may be used, the present construction of burner being, however, more particularly adapted for use with a fuel mixture of the character set forth in the abovementioned copending application which as therein stated is a mixture of a heavy oil and air in an atomized state and propelled at a relatively high velocity against a hot spot.

This mixture is led through pipe 29 to a spout or discharge nozzle 31 so disposed within the chamber 13 as to discharge the mixed fuel against the downwardly extending curved portion 32 of the pocket 13, which portion is disposed directly in the path of the heat waves emanating from the fire pot, thereby attaining a very high temperature. It is to be noted that the downwardly extending portion 32 of the pocket 13 is disposed considerably nearer the burner nozzles than the conduits 12, whereby the portion 32 attains a higher temperature than the conduits, although the latter are maintained at a suliiciently high temperature to prevent the gases formed within the chamber 13 from condensing.

The portion 32 is termed the hot spot of the burner and when the mixture is projected thereagainst it is broken up or cracked and divided into its more volatile constituents and thus converted into a highly gaseous state so that when discharged from the burner nozzle 17 a substantially complete combustion is attained and no objectionable or deleterious carbon deposits upon the furnace walls result. The highly active state of the gases generated in the pocket due to the hot spot leave the passages free from becoming clogged with solid residues. it has been found that only after long and severe use it may be found necessary to brush off the walls of the conduits. For this purpose threaded plugs may be provided to permit access to the conduits when desirable.

The spout or discharge nozzle 31 may be provided with a flange having arcuate slots 35 for the passage of tap bolts 36 into threaded holes in a seat 37 integral with and common to the several conduits 12. By reason of the slotted flange 31, an elbow portion 37 of the discharge nozzle 31 may be adjusted about a central axis of the burner thus imparting flexibility to the structure and facilitating installation. It will be :1 preciated that the discharge nozzle may cusily be removed and the pocket inspected when desirable; or nozzles of different outlet area may be substituted one for another if it is desirable to vary the volume and velocity of the mixture discharged against the hoi spot.

The burner nozzle con'iprising the perforated member 17' is obviously subjected to the most wear and may be made of any hard material such as Monel metal or the perforations may be provided with peripheral reinforcements of such metal or other heat resistant substance. By virtue of the present construction, the nozzle member may, however, be quickly and cheaply replaced without the necessity of disassembling the other elements of the burner.

The present invention therefore contemplates a burner of such construction as to meet favor for domestic use as well as for use in connection with high pressure heating or other systems. The simplicity of the tire pot and its adaptability to meet a great variety of conditions has demonstrated the fact that it is a decided advance step in the art of fuel heating units.

Although a preferred embodiment of my burner has been illustrated and described, it is to be appreciated that persons skilled in loo llU

till

menses the art may malre modifications therein, but

such modifications as come within the terms of the appended claims are contemplated by me as falling within the spirit and scope of my invention. v

l l hat l claim is:

i. ll, fluid fuel burner comprising a manifold for guiding fuel in a plurality of paths, or fire pot consisting of intersecting channels, said manifold and fire pot being in communication, and a removable nozzle member positioned in said channels.

it. A fluid fuel burner comprising a pocket, means for feeding fuel to said pocket, a lire pot consisting of intersecting troughs and communicating conduits between said poclret and said fire pot.

8, A fluid fuel burner comprising an enpansion chamber, a fuel ignition chamber having a plurality of channels intersecting at a. common point, said channels being di vided transversely to provide a removable upper section, and a removable nozzle member for discharging fuel in said channels.

a A fluid fuel burner comprising an expansion chamber, a fuel ignition chamber comprising a plurality of intersecting channels consisting of an upper and lower section and a nozzle member adapted to be positioned in communication with said channels.

An oil burner comprising a plurality of inverted substantially tl-shaped supply conduits and a cruciform lire pot connected thereto.

it An oil burner comprising a plurality of inverted substantially U-shaped intersecting supply conduits, a downwardly extending chamber disposed at the intersection of said conduits, and a the pot connected to said conduits and so disposed with respect to said chamber as to intensively heat the same when the burner is in operation.

it, An oil burner comprising a plurality of intersecting conduits, a downwardly pro jeoting chamber disposed at the intersection of said conduits, and a cfuciform fire pot connected to said conduits.

8. An oil burner comprising a plurality of intersecting conduits, a fuel supply nozzle entering said conduits at the intersection thereof, and a cruciform lire pot connected to said conduits.

9. An oil burner comprising a central chamber, a plurality of conduits having portions thereof extending outwardly and up wardly and then downwardly from said chamber, a supply conduit angularly adjustable connected. to said chamber, and a the pot connected to said conduits.

10. An oil burner comprising a plurality of outwardly and downwardly extending conduits intersecting one another to form a central chamber, a cruciform fire pot con nected to said conduits, a heat resistant lining for said lire pot adjacent its sides and burner openings in said fire pot some of which are adapted to maintain said lining heated, others of which are so disposed as to project a flame in line with the upper edge of said lining and others of which are so disposed as to direct a flame vertically with a portion thereof adapted to heat said cen tral chamber to a high temperature.

ll. An oil burner comprising a plunlity of supply conduits, a cruciform fire pot con nected to said conduits and removable fire briclr within said lire pot to form. a lining therefor,

12. An oil burner comprising a plurality of supply conduits, a cruciform fire pot connected to said conduits, and a removable lire briclr lining for said fire pot, said lire brick having flaring faces.

In testimony whereof, I have hereunto subscribed. my name this E/Z lth day of July, Hillel,
